If you create the RAID 0 in striped mode then the read/write speed for large files is substantially increased. I believe, in the region of 70% -> 80%. However I can't remember exactly off the top of my head. However, if you don't use striped raid 0 (if you loose a disk there is a marginally better chance of recovering data). Then there is absolutely NO speed performance, but you do get larger volumes. -- Douglas Furlong Systems Administrator Firebox.com T: 0870 420 4475 F: 0870 220 2178
